Injecting reactive separate components into blood vessels - using needles terminating in common inclined plane for rapid mixing

摘要

Two or more components to be injected into a patients blood vessels, in order to react and control blood supply are delivered to a catheter (1) by a corresp. no. of tubular hoses (4, 5 :17) leading from the terminals (6, 7) in a coupling housing. At the ends of the injection needles, the outlets for the components and a single inclined plane (30) at which the components commence their interaction. One hose may extend within an outer hose, and the needles may be concentric or attached lengthwise to each other. ADVANTAGE - Components are promptly well-mixed, with no risk of premature hardening.
